Warrant terms and provisions

In September 2013, we raised $6.6 million before issuance costs of approximately $434,000 from the sale of 3.5 million shares of common stock and warrants to purchase up to an aggregate of 2.1 million shares of our common stock in a registered direct offering. The warrants have an exercise price of $2.444 per share, a five year term, and are exercisable beginning on the date of issuance. Each warrant to purchase a share of common stock may also be exchanged during its term for a number of shares of common stock (but not more than one share of common stock for each warrant so exchanged) with a value determined by a negotiated formula if, among other things, our common stock is then trading at a price at or lower than the warrant exercise price per share. Subject to limitations in the warrants, we may require the warrants be exercised for cash if the closing bid price of our stock is over $3.055 for 20 consecutive trading days and the average daily dollar volume over that period is equal to or exceeds $300,000.

In May 2013, we raised $5.85 million before issuance costs of approximately $362,000 from the sale of 2.6 million shares of common stock and warrants to purchase up to an aggregate of 2.0 million shares of our common stock in a registered direct offering. The warrants have an exercise price of $2.886 per share, a five year term, and are exercisable beginning on the date of issuance. Each warrant to purchase a share of common stock may also be exchanged during its term for a number of shares of common stock (but not more than one share of common stock for each warrant so exchanged) with a value determined by a negotiated formula if, among other things, our common stock is then trading at a price at or lower than the warrant exercise price per share. Subject to limitations in the warrants, we may require the warrants be exercised for cash if the closing bid price of our stock is over $3.61 for 20 consecutive trading days and the average daily dollar volume over that period is equal to or exceeds $300,000.
